To all whom 'it may concern:

Be it known that I, ARTHUR W. SMITH, citizen of the United States, and resident of the borough of Manhattan, city of New York, in the 'county of New York and State of New York, have invented certain .new and useful Improvements in Type-'Writlng Machines, of which the following is a specification. i

My invention relates to typewriting machines and more particularly to type carriers and to means for attaching type blocks thereto.

The main object of the inventlon, generally st-ated, is to provide simple and eificient means for 'attaching type ,blocks to type bars or carriers, and to provide a construction which may be manufacturedl at a. small cost andmloy which the type bar and block may be i'e'adily and eificlently united. p

Afurther object of my inventlon 1s to provide means of the character speclfied m which an adjustment of the type blocks onthe type bars or carriers may be eifected.

To the above and other vends which will appear from the following specificatlon, my invention consists in the features of construction, arrangements of parts and combinations of devices which will be hereinafter more fully described and particularly pointed out in the appended -claims In the accompanying drawmgs, whereln like .reference characters -indicate o corresponding parts in the various views, Figure 1 is a detail side .view of a type bar and type block embodying my invention. Fig. 2 is a detail fragmentary side v1ew of the same with parts sect-ioned away, the section being taken on a line 'v-'v of Fig. 4 and looking in the direction of the arrows at said line. Fig. 3 is a transverse sectional view. of the same taken on ay line 'ttu of Fig. 2 and looking in the direction of ,the

` fragmentary detail side view of a modified form of vtype bar and type block with parts sectioned away, the section being taken on a line iii-dw of Fig. 7 and looking in the direction of the arrows at said line.- The view shown in'Fig. 5 corresponds to that represented in Fig. 2, exce t that Fig. 5 shows av modified form of' construction.

taken on a line w-m in Fig. 5 and` looking in the direction of the arrowsat said line. Fig. 7 is a top plan view of the type block shown in Figs. 5 and 6. Fig. 8 is a top plan view of a still further modified form of construction. Fig. 9 is a transverse sectional view of the parts represented in Fig. 8, the section being taken lon the line of Fig. 8 and looking in the direction of the arrows at said line. The type pcarrier 1 in the present instance 1s shown as a type bar stam ed from sheet metal and having parallel sidbs and a pivot opening 2 therein and an opening 3" by' whlch connection may be made between the type bar and suitable type bar actuating devices. 4

vReferring to Figs. 1, 2, 3 and 4, it will be seen that the upper or front edge of the type bar is fiat or straight at points 4 and that mtermediate these flatportions are upwardly extending integral lugs, studs or projections 5 which extend from the front edge of the bar. The thickness o'f these lugs 5 .in the first instance correspo ds to the thickness of the type bar'or to that portion`` side members 9 with parallel inner' side" wallsv spaced apart to `correspond to' the' thickness of the metal from which thetype. bar is made at the end `thereof to-whiclr the type block is afixed...In other words,- the width of the slot 7 Vin the type block is such that it will receive iWith a snug fit the frontedge of the type bar when the block straddles the bar, as shown in'Figs. 2 and 3. One or more openings 10 extend transverselythrough the 'type block, the number of such openings depending on the number of studs or lugs 5 that are' provided on the type bar. As shown in Figs. 2 and 4 there are two studs 5 provided on the front edge 'of the bar, and a 'corre'sponding number of openings. 10 are provided to receive said studs when the block is in placeon the bar.

received. By this arrangement a limited exte'nt of adjustment of the .type block on the type bar, and longitndinally of the latter, may be etfected before the block is secured in place; whereas each side member 9 of the type block bears against the side of the type bar to prvent any lateral movement of the block relatively to the bar but aiford an adjnstmentof the block longitudinally of the bar. When the type block has been placed in position straddlingthebaras shown, and with the portions 5 of the type bar received in the openings 10 in the block, after the block is'adjnsted to proper positionon the bar, a suitable tool may be employed to expand the metal from which each projection 5 is formed, so a to provide a head 01' laterally extending'bnr '11 which overlaps the type block and closes the month of the corresponding opening 10, as shown in- Fig.

This causes the type bar and block to interlockwith each other and causes the type block-'to be secnrely fastened to the bar. It

nnderstoojd that when each projection 5 on the type bar -yis headed, as at 11, to close the assoiate', opening 10 in the manner described, the type block will be securely held\ against detachment from or The bottom wall of lthe long'itudinal slot 7 in the block will at this time be firmly held against the flat- -"tened portionsa on the'type bar. In short the body portion of the block bears against the front edge of the bar so that there is no tendency to di'slodge the block from the bar nor to strain and loosen the headed connection by the impact of the block against the platen. Moreover, it will be understood that the openings 10 in the type block extend at snbst'antially right angles to the length of the slot i" therein, so that the projections 5 limit the sliding adjustnient of the block longitudinally of the bar, and prevent v the'block from being withdrawn from the bar longitndinally IthereOf.

In Figs. 5, .6 and 7 I have shown the modified form of construction in which the openings 10a extend to the front face 12 of the type block 6a, and the inner' walls of each opening 10a are inclined npwardly and outwardly at the upper portions thereof, as indica'ted at 13 in F ig. 6. Each stnd, lug or projection 5a which is received within an opening 10a extends to a point where it is flush with the front face 12 of the block. Afterlthe block is inserted in place on the bar landad'iusted longitndinally thereof, afsuitable tool maybe employedto expand the metalufrom which the projections 5a are formed-,- as indicvated in Fig..6. If desired, the metal o'f the projections 5a may 'be split three types 8 or 8u on a bar and twofastening stnds 5 or 5n which connect each block to its bar. In Figs. 8 and 9 I have shown a type block 6b provided with but two types 8b. In this construction a single opening 10h extends transversely through the type block and receives a stud, lugr or projection 5b which extends from the front edge of the type bar 1b and is headed or riveted over the month of the opening 10'), as indicated at 11h, to effect an interlockingr engagement between theztype bar and type block. Like the constructions shown in the preceding figures the type block shown in Figs. 8 and 9 is slotted to receive and straddle the type bar. In'this modified form of construction, like those shown in the preceding fignres, the stud 5b is smaller, considered longitndinally of the type bar, than the opening 10b in which it is received, so to a'lford an adjustment of the type block on the type bar longitudinally of the latter. Moreover,

the integral stud 5b on the type bar is received in an opening in the type block 6b intermediate the types thereon.

' From the foregoing description it will be nnderstood that I have provided simple and. eiicient means for effectively connecting a type block to a. type bar or carricr and that the construction is such that it cnables the parts to be made at eoniparatively small cost and there is no liability of a type block bcing-accidentally displaccd on or from the bar after the block is secured in place. It will be seen that the type bar, the type block and t-he means by which the two are connected comprise only two members. the block and the bar, and that. 'these two members are forined for interlocking engagement with each other in such a manner that the block may be' rigidly'secnred to the bar. There are no screws or threadcd conncetions for a-ttaching one member to the other and the simplicity of the construction enablcs it to be made at small cost'without, however, detracting from the eifectiveness of the constrnction.

Various changes may be made .without departing from the spirit and scope of my invention.

What I claim as new and desire to secure by Letters Patent, is

1. The combination of a type bar; and a type block, the body of the type block bearing against the body of the type bar and one of said members having an opening therethrongh and the other member having a prevent a detachment of' the an integral part that extends through said opening and is enlarged at the mouth of the opening to form an interlocking engagementbetween the type bar and the type block. v
